Designed for demanding observatories an instrument load of 100 kg (OTA excluding counterweights), the GM 3000 HPS combines sub-arcsec absolute encoders, 100 % CNC mechanics and an on-board Linux controller.
ATTENTION: Due to the weight and size of the frame, shipping must be on a pallet. To validate your order, you must add to your basket the "Shipping kit for GM3000", which contains:
These two elements secure the mount during transport and are then used to install it in your observatory.
